Your brain learns during sleep – Study

I think sleep may be the most under-appreciated aspect of living a healthy life. Diet and exercise and well-known if not often followed, but sleep is often thought of as an intrusion in our busy lives. I know that back when I was in the working world, I certainly thought of it that way.

Scientific data suggests that all animals probably do sleep—including the most unexpected creatures, such as fish, birds, worms, and flies. Sara Aton, University of Michigan ssistant professor in the Department of Molecular, Cellular, and Developmental Biology, can attest to dozing cats, mice, and even cuttlefish, all of which she’s studied as they snoozed. She marvels that biologists once thought bugs and birds and worms never slept.

“I think there’s this pervasive misconception that your brain is just turning off when you go to sleep, because there’s no obvious output. Outside of a coma, you can’t think of a less interesting behavior to study than sleep, right?” Aton says. “Sleep is something that, as humans, we spend a third of our life doing. And yet biologists and the neuroscience community didn’t have a lot of interest in it.” (my emphasis)

But now that we know better, new questions arise: Do animals all rest for the same reasons?
After studying sleep for the past decade, Aton is convinced that it matters—a lot. “I’m much more protective of, for example, my son’s sleep than I would have been had I not been in this field,” she says.

10 Hidden Anxiety Triggers You Need to Avoid

There is a ton of good information in this. Read it and reap!

Super tools for handling stress

Tony

Our Better Health

Anxiety seems to be a near-universal condition. In the United States alone, approximately 40 million adults – or 18 percent of the population – suffer from an anxiety disorder.

And these numbers represent only the diagnosed (i.e. reported). The actual number is likely to be significantly higher.

The truth is that society is somewhat to blame (not to negate our own sense of responsibility.) We’ve managed to build a 24/7 “constantly connected” infrastructure that has permeated into schools, businesses and elsewhere. Many people are under constant pressure to succeed; most ironically by leveraging this very infrastructure. This only exacerbates the problem.

“Prevention is the best cure” is a universal axiom within the medical community, including within the mental health sphere. Understanding what “triggers” certain symptoms or condition can – in some instances – drastically reduce the likelihood of a symptom or episode.

Here, we focus on ten established “triggers” that…

Sleep Trackers Can Prompt Sleep Problems

I wrote just three days ago in my post on sleep mistakes, “Sleep is one of the truly under-appreciated aspects of living a long and healthy life….” So, I sympathize with anyone taking steps to improve their sleep. It turns out, however, that using some of the new devices can have a negative impact on your overnight rest. The following is from the Rush University Medical Center.

A 39-year-old man whom we’ll call Mr. R received a sleep-tracking device from his girlfriend. Since starting a new job several years earlier, he sometimes had trouble getting a good night’s sleep. Not surprisingly, the next day he’d feel tired, irritable and absentminded.

A man sleeping

Based on data generated by his girlfriend’s gift, Mr. R concluded those symptoms occurred only after he failed to get eight hours of sleep the night before. He set himself an ambitious goal: “to achieve,” as he later told a therapist, “at least eight hours of sleep every night.”

His gauge for deciding whether he had succeeded: his new sleep tracker. And so each night, Mr. R went to bed feeling the pressure of ensuring that the next morning the tracker would display the desired eight hours — a self-induced level of increasing anxiety that’s hardly the ideal recipe for achieving a sound night’s sleep.

The Sleep Cure: The Fountain of Youth May Be Close at Hand

I couldn’t agree more with these healthy sleep sentiments. Check out my Page – How important is a good night’s sleep for more details.

Mark Zielinski knew he was onto something when his mice stopped sleeping. Normally, the animals woke and slept on a 12-hour cycle. When the lights were on in the lab, the mice were active. When it went dark on a timer, down they went. But Zielinski, who teaches psychiatry at Harvard Medical School, had recently […]

What is Good Quality Sleep? – NSF

Regular readers know I feel strongly about the value of a good night’s sleep. I have a Page on it – How important is a good night’s sleep?

I consider it to be truly one of the most under-appreciated aspects of good health.

The National Sleep Foundation (NSF) recently released the key indicators of good sleep quality, as established by a panel of experts.

brain

Given the precipitous increase in the use of sleep technology devices, the key findings are timely and relevant. This information complements the data these devices provide, helping millions of consumers interpret their sleep patterns. The report comes as the first step in NSF’s effort to spearhead defining the key indicators of good sleep quality. They key determinants of quality sleep are included in a report published in Sleep Health. They include:

  • Sleeping more time while in bed (at least 85 percent of the total time)
  • Falling asleep in 30 minutes or less
  • Waking up no more than once per night; and
  • Being awake for 20 minutes or less after initially falling asleep.

Multiple rounds of consensus voting on the determinants led to the key findings, which have since been endorsed by the American Association of Anatomists, American Academy of Neurology, American Physiological Society, Gerontological Society of America, Human Anatomy and Physiology Society, Society for Research on Biological Rhythms, Society for Research of Human Development, and Society for Women’s Health Research.

Bad habits that can hurt your brain – WebMD

I  write often about the benefits the brain gets from exercise and how we should make regular exercise a priority as much for our mental health as physical. That is a good positive target.

It turns out that WebMD also has some excellent suggestions for keeping our brains clicking on all cylinders, but they approach from the negative side. Not doing harmful things is also an important consideration in getting to old age with a fully functional brain.

Here is their list of bad habits:

Missing out on sleep. WebMD notes, “… lack of sleep may be a cause of dementia, including Alzheimer’s disease. It’s best to have regular sleeping hours. If you have trouble with sleep, avoid alcohol, caffeine, and electronics in the evening, and start a soothing bedtime ritual.”

Portions of the Brain Fall Asleep While we are Awake …

I am blown away by the brain and how it functions in our body and allows us to function. Remember, the brain which accounts for about two percent of our body weight burns around 25 percent of the calories we use in a day. This item from Neuroscience News moves the needle further.

When we are in a deep slumber our brain’s activity ebbs and flows in big, obvious waves, like watching a tide of human bodies rise up and sit down around a sports stadium. It’s hard to miss. Now, Stanford researchers have found, those same cycles exist in wake as in sleep, but with only small sections sitting and standing in unison rather than the entire stadium. It’s as if tiny portions of the brain are independently falling asleep and waking back up all the time.

brain-sleep-wake-neurosciencenews-public.jpg

What’s more, it appears that when the neurons have cycled into the more active, or “on,” state they are better at responding to the world. The neurons also spend more time in the on state when paying attention to a task. This finding suggests processes that regulate brain activity in sleep might also play a role in attention.

“Selective attention is similar to making small parts of your brain a little bit more awake,” said Tatiana Engel, a postdoctoral fellow and co-lead author on the research, which published Dec. 1 in Science. Former graduate student Nicholas Steinmetz was the other co-lead author, who carried out the neurophysiology experiments in the lab of Tirin Moore, a professor of neurobiology and one of the senior authors.

Poor sleep may raise risk for irregular heart rhythms – AHA

Regular readers know that I feel strongly that sleep is one of the cornerstones of good health. You can check out my Page – How important is a good night’s sleep? for more details.

According to the American Heart Association (AHA):
• Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat.
• In addition, getting less rapid-eye movement (REM) sleep may also be linked to higher atrial fibrillation risks.

5 Ways to keep your memory sharp – Harvard

Regular readers know that I am a senior citizen; will be 77 in January. So, I have a lot of senior friends. We have all experienced ‘senior moments’ when we find our memory becoming slightly elusive. Because my family has had Alzheimer’s and other forms of dementia I am particularly sensitive to any brain stuff. So I was impressed with the suggestions that Harvard brought forward regarding enhancing our memory.

The way you live, what you eat and drink, and how you treat your body can affect your memory just as much as your physical health and well-being. Here are five things you can do every day to keep both your mind and body sharp.

1. Manage your stress. The constant drumbeat of daily stresses such as deadline pressures or petty arguments can certainly distract you and affect your ability to focus and recall. But the bigger problem is an ongoing sense of anxiety — that can lead to memory impairment. If you don’t have a strategy in place for managing your stress, protecting your memory is one reason to get one. Deep breathing, meditation, yoga, and a “mindful” approach to living can all help.

I have posted a number of times on stress. You can find them by searching s t r e s s in the box at the right. If you want one excellent example check out: Super tools for handling stress.

STAYING HEALTHY WITH AYURVEDA

According to Ayurveda, our potential for good health depends largely on how we live our day-to-day life. It is our patterns of eating, sleeping, exercise and what we do daily to rejuvenate ourselves that help determine whether we maintain vibrant health throughout our lifetime.

Ayurveda recognizes the importance of our relationship with the universe around us. We are a part of nature: if we live in accord with the laws that structure the world we live in, we can keep our mind/body system functioning efficiently with the least amount of wear and tear.

One key to living in tune with nature is the time that we go to bed and get up in the morning. There is a saying, “The day begins the night before.” Only by going to be early in the evening can we start the next day fully rested, having synchronized our individual rhythms with the circadian…

9 Reasons To Eat Honey Daily

I was lucky enough to be exposed to some of these facts about honey years ago. Been using it ever since.

Honey

Tony

Our Better Health

 The possible health benefits of honey have been documented in early Greek, Roman, Vedic, and Islamic texts and healing qualities of honey were referred to by philosophers and scientists all the way back to ancient times, such as Aristotle (384-322 BC) and Aristoxenus (320 BC). – Joseph Nordqvist, Medical News Daily
For something that tastes so good, honey isn’t consumed all that often. Besides being delicious, honey is also densely packed with valuable nutrition, such as nutrients. Honey is also quite healthy: a tablespoon of raw, unadulterated honey contains 64 calories, and is free from cholesterol, fat, and sodium.
The ideal nutritional composition of honey almost assuredly helps give the natural sweeter its health-promoting properties. Here, we’re going to discuss nine such health benefits of this sweet nectar.

Our Better Health

In a hyper-competitive world overflowing with information, our brains need to be able to keep up and outpace our competitors. Who doesn’t want their brain to process faster, remember more information or be able to come up with elegant solutions to complex problems? Cogito ergo sum. I think therefore I am. Our brains more or less define our existence and who we are. So how can we get our brains to work better, faster and more efficiently?

HERE ARE SEVEN HABITS THAT WILL HELP IMPROVE YOUR BRAIN FUNCTION:

1. EXERCISE REGULARLY

Exercising promotes blood flow, cardiac health and releases beneficial hormones and proteins into your body. These hormones and proteins protect your neurons, which are the cells that make up most of your brain, and encourage them to multiply and make new connections. Studies have shown that exercise helps you learn faster and remember more information. Further studies have shown…
